[Spigelian hernia: apropos of two cases].

Two observed cases of spigelian hernias in 54 years and 62 years old men leads to an analysis of the diagnostic clinical and therapeutic aspects of this rare abdominal pathology. It represents 1-2% of all abdominal hernias and can occur anywhere along the semicircular line of Douglas, but in 90% of cases its most frequent localization is from the level of the umbilicus to the inguinal area. Diagnosis can be difficult because of non-specificity of symptoms. Many times Spigelian hernia is masked by abdominal fat and the only symptom is pain. TAC plays a primary role in the diagnosis of spigelian hernia, infact with it, detailed characteristiques and location of the hernia, hernial content, other intra-abdominal pathology, are recognized. The only treatment of spigelian hernia is surgical; many times it is diagnostic and therapeutic. A pararectal skin incision permits an accurate exploration of the abdominal cavity and an cautious choice of aponeurosis to the plastic repair.
